Well, to keep it short - just go ahead and stutter. :) We can certainly avoid certain words, if we think they'll cause problems, but we can also choose to keep saying them. I don't necessarily have particular specific words that are always causing problems, because that sort of thing tends to come and go, depending on where my stutter is at (at any given moment). Sometimes, we choose other words out of convenience. But I prefer sticking to those that I intended. It makes me happier, I think, even with the likelihood of stuttering. :)
